Power Subsidies and Groundwater Use

August 14, 2019

What is the issue?

  • The attempt to use power subsidy to control groundwater extraction, as in Punjab, ignores certain ground truths.
  • Here is an overview of the concerns with groundwater use and the shortfalls with the Punjab model.

How is electricity a factor?

  • Groundwater overdraft is also linked to subsidised power supply to agriculture.
  • So, the mode of electricity pricing supplied to agriculture could be changed to control groundwater abstraction.
  • This can in turn help achieve the goals of efficiency, equity and sustainability.
  • The most frequently suggested instrument for controlling groundwater abstraction was the metering and pro-rata (proportional) pricing of electricity.

What is the Punjab model?

  • An idea which came from a prominent research group recently is direct delivery of power subsidy to agriculture.
  • It involves metering of agricultural power connections, but no metered tariff.
  • The idea is to make sure that farmers get free power.
  • But, the power utility reduces its subsidy burden gradually by incentivising the farmers to use less electricity.
  • It thereby saves both groundwater and electricity.
  • This model was adapted by the power utility of Punjab.
  • It involves offering cash incentives to well-irrigating farmers who use less than a designated quota of electricity each season.
  • The individual’s quota is decided on the basis of the connected load and the season.
  • E.g. for one HP of connected load, a farmer is entitled to 200 units a month during the kharif season and 50 units per month during the winter
  • The farmer gets a cash incentive of Rs. 4 for every unit of electricity saved.

What is the downside of this?

  • This pilot project implemented in 135 farms across Punjab has shown reduced electricity consumption by around 60% of the farmers.
  • However, nearly a third of the farmers had increased electricity consumption even after accepting the scheme.
  • Reason - In a given year, season and locality, the power demand will be a function of the cropped area and cropping pattern.
  • Fixing the quota is on the basis of connected load.
  • This can be said to be rational only if the farmers have correctly chosen the pump capacity.
  • They should have taken into consideration the actual quantum of energy required for irrigating farm and the number of hours that the power supply is available.
  • But this may not be the case in reality.
  • Possibly, many resource-rich farmers have chosen over-sized pumps.
  • In such cases, their energy quota will be much higher than what is required to irrigate the plot even at the current excessive levels of dosage.
  • The reason for maintaining the high-level of irrigation dosage is that it could be rewarding from an economic perspective, yield improvement.
  • The value of this is logically more than the economic incentive they get by saving water.
  • In effect, resource-rich farmers might keep their power consumption much below the ‘quota’ and claim cash incentive, but continue with inefficient irrigation.
  • On the other hand, a resource-poor farmer, who has a low-capacity pump might end up using the full quota of energy or even more.

What is the way forward?

  • Ideally, the ‘energy quota’ should have been fixed on the basis of the actual land holding cultivated by the farmer during a particular season.
  • It is this that determines the water and energy requirements for irrigation.
  • The point is that the current subsidy structure may not create any special incentive to save either electricity or groundwater in Punjab.
  • The irrigated paddy fields as well as rainfall contribute to the recharging of shallow groundwater during the monsoon season in alluvial Punjab.
  • So, besides regulating irrigation, addressing rainfall infiltration is also important.
  • Also, choosing a crop or variety with lower evapo-transpirative requirement is essential to conserve soil moisture.
  • All these require coordination among various departments - water resources, electricity and agriculture.
